WALTER W. VVINTON, OF SCRANTON, PENNSYLVANIA.

INHALER.

SPECIFICATION forming part of Letters Patent No. 645,741, dated March20, 1900.

Serial No. 719,365. (No model.)

To all whom it may concern:

Be it known that I, WALTER W. WINTON, a citizen of the United States,residing at Scranton, in the county of Lackawanna and Stae ofPennsylvania, have invented certain new and useful Improvements inInhalers, of which the following is a speciiication, reference being hadtherein to the accompanying drawings.

This invention relates to inhalers, such as are applied to the nostrilsfor the purpose of inhaling medicaments; and the objects of theinvention are to provide an improved form for such inhalers7 a perfectsea-ling instrument of the kind, a more convenient receptacle formedicaments, to make them more easily replenished, and other objects asare set forth herein and embodied in the claims.

To this end the device consists of the construction, arrangement, andcombination of parts herein described, and illustrated in theaccompanying drawings, in which- Figure 1 is a View of one of myinhalerscut .elevation of the interior parts of my inhaler, showing themedicinal-salt receptacle partly disconnected. Fig. 3 is an exteriorview of one of my inhalers in the closed position. Fig. 4 is a view incross-section taken on the line @c a; of Fig. 1. Fig. 5 is a view of theinterior parts of my inhaler when a saturated fabric is substituted fora salt-receptacle.

Similar figures of reference denote like and corresponding partsthroughout the several views. Y

In the drawings, 1 designates a cylindrical case of a convenient sizesuitably tapered at 2 to t the nostril. The small end of the case 3 isclosed by the small hemisphericalvalvelid 3 on the end of a stem 4,which extends centrally and longitudinally through the case. The stem 4has a screw-threaded shank connecting it with a plug 5, which plug isadapted to close the larger end of the case at the same` time that thevalve-lid 3 closes the smaller end. The adjustment of the stem 4 may beaccomplished by screwing it farther into or out of the said plug untilthe exact proper length is had. The larger end of the case is alsointernally screw-threaded, and a part of the plug 5 is threaded toengage with it 5 butv Fig2 is a detailV the threads are grooved out inseveral lines, as at 6 6 6, and a neck 9 is turned on the plug withwhich the grooves 6 communicate. A milled knob 8, having a iiatinwardly-facing annular surface 7, is formed on the outer end of theplug and serves as a handle in opening and closing the device. Disposedcentrally on the stem 4 is a medicine-salt receptacle 10, cylindrical inform and of a little smaller diameter than the interior of the case,

outer walls and the inner walls of the case. Bore-holes 12 12, 85o., inthe ends and side walls of the receptacle serve to promote infusion ofthe contents into the air drawn through the inhaler. In one end of thecylinder 10 is a central aperture, through which the stem 4 may slide.The other end is internally screw-threaded to receive the screwthe stem4 by means of a pin 14.

The operation of the device may now be eX- plained. The cylinder 10 isfilled with medicinal salts, such as are used in inhalers, by unscrewingthe cylinder, as shown in Fig. 2, and suspending it by holding the knob8 between the thumb and linger, in which position the salts may bepoured into the cylinder. The plug 11 is then screwed in through the endof the cylinder by turning the stem by means of the knob 8. The whole isthen inserted in the larger end of the case and the plug 5 screwedinward until the face 7 rests tightly on the rim of the larger end ofthe case, the valve-lid 3 at the same time tightly closing the orifice3' at the small end of the inhaler. When it is desired to use theinhaler, a slight turn with the thumb and finger will produce a flatopening between the rim of the inhaler and the knob 8 and at the sametime open the small end of the inhaler. The medicaments may then beinhaled in the usual way. When a liquid medicament is to be used, thereceptacle 10 and plug 11 may be dispensed with and a more suitablefabric 15 may be wrapped about the stem 4 and secured with wire or otherfastenings 16, and

the inhaler is made effective and convenient, perfect cleanliness ismaintained, and a perfeet closing case is assured.

threaded plug 11, which may be fastened to then saturated. Thus thereplenishment of so as to leave free access of air between its IOOHaving thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In an inhaler, the combination of a cylindrical case with acontracted end having an opening at said contracted end, and beinginternally screw-threaded at the other end and adapted to be closed by ascrew-threaded plug,a screw-threaded plug having air-grooves cutting itsthreads transversely, a central shaft extending from the said pluglengthwise through said cylindrical case to the contracted end, andbeing there provided with a knob adapted to completely close the saidcontracted end simultaneously with the plug end when the plug is screwedhome, and a medi'- cine-receptacle axially mounted on said shaft andremovable from the case therewith; substantially as specied and for thepurpose set forth.

2. In a new article of manufacture an inhaler comprised in thecombination of a cylindrical case having a contracted end with anopening therein, and being internally screwthreaded at the other endwhich is adapted to be closed bya screw-threaded plug having a centralshaft extending from it to the contracted end, a ku'ob on the fartherend of said shaft adapted to close the contracted end simultaneouslywith the plug end when the plug is screwed home, and the said centralshaft being further providedwith a cylindrical medicine-receptacleaxially mounted and slidable thereon, the cylindrical sides thereofbeing perforated to permit saturation, a lid rigidly secured to saidcentral shaft being adapted to fix the location of said receptacle andclose it when filled with medicament, all arranged for joint operationin the manner and for the purposes specified.

In testimony whereof I affix my signature in presence of two witnesses.
